THEORY OF OPERATION INTRODUCTION PM-180V,SM2102E are 99 channel portable FM transceiver constructed with a microprocessor controlled, temperature compensated Phase Locked Loop (PLL) frequency synthesizer. The radio features a double conversion receiver and a direct FM transmitter modulator. A special integrated circuit provides support to sub-audible signaling (CTCSS & DCS) and most of the receiving parts are switched off periodically in the power saver mode to reduce battery current drain during standby. The Block Diagram RF and Control Circuit Diagrams for PM-180V,SM2102E shall be used in associate with the following circuit description. CIRCUIT DESCRIPTIONS 1) PHASE-LOCK LOOP (PLL) CIRCUIT

* REFERENCE OSCILLATOR The reference oscillator in the Frequency Synthesizer IC601, uses the TCXO631 as a stabilized source of 15.3MHz. The reference oscillator frequency drives the divider in the Frequency synthesizer to produce a comparison frequency. This comparison frequency is selected by decoding the first three bits of the data input from microcomputer.

* PROGRAMMABLE DIVIDER The programmable divider in IC601 divides the VCO output . It consists of a two-modulus pre-scalar with a 7bit control register followed by a 11-bit internal programmable divider. The overall division ratio is selected by a single 19-bit word located on the serial data bus.

* PHASE COMPARATOR The digital-type phase comparator in IC601 compares the divided VCO frequency with the comparison frequency. It generates a correction voltage that is applied to a low-pass filter consisting of R621-

R623,R624, C617,C618, C620. This voltage is applied to the VCO circuit. The phase comparator also provides the lock detect signal .

* VCO CIRCUIT The VCO circuits contains a separate RX VCO (Q521,D511,D512) and TX VCO

(Q541,D531,D532,D533,D534). The oscillated signal is amplified at the buffer amplifiers

(Q571,Q572)and is then applied to the T/R switch (D901,D902). Then the Receive 1st LO (Rx) signal is applied to the 1st mixer (Q801)and the transmit (Tx) signal to the amplifier circuit ( Q901). A portion of the signal from the buffer amplifier (Q571) is fed back to the PLL IC) via the doubler circuit

(Q591) as the comparison signal. 2) TRANSMITTER

* MIC AMP CIRCUIT Voice signal from the microphone are applied to microphone amplifier IC305. IC306 is configured as a low-pass filter that has a 6dB/oct response between 300Hz and 3kHz. The microphone audio signal is amplified by IC305-A, with R351 and C347 on the output providing pre-emphasis. The microphone audio signal is then fed to switch IC304 on pin 4 and the switched output signal is on pin 3. This signal is then applied to high-pass filter IC306- D,-C which attenuates frequencies in the Call Guard (CTCSS/DTCS) range. This is the same filter used for receive audio filtering. The signal is then fed to IC306-B and IC306-A which provide buffering and amplification. 10 PM180V / SM-2102E SERIES MOBILE Deviation limiting is then provided by level controller IC307. The input to this device is pin 16 and the output is pin 15. The signal is then fed to splatter filter IC303-A and switch IC304-C. The input is on pin 8 and the output is on pin 9. The modulation signal is then applied to the PLL circuit as MOD.

* VCO AND AMPLIFIER The VCO signal output is switched by diodes D901 and then amplified by Q901, Q902, Q911,Q912 and then fed to power amplifier Q931.

* POWER AMPLIFIER CIRCUIT Q931 is provided with approximately 13.2 VDC power source. The power detector circuit D991 detects the transmit power output level and converts it into DC voltage.The output voltage is at a minimum level when the antenna impedance is matched with 50 and is increased when it is mismatched. The detected voltage is applied to the differential amplifier IC761, and the TURN_2 signal from the D/A converter controlled by the MCU is applied to the other input for reference. When antenna impedance is mismatched, the detected voltage exceeds the power setting voltage. Then the output voltage of the differential amplifier IC761 controls the input bias voltage of the drive ; Q911,Q912,Q931 The signals from Q931 is supplied through a low-pass filter made up of L973, L974, L975 and C975-C979, C981 to antenna switch D971 then applied to Antenna Connector. 3) RECEIVER

* ANT SWITCHING CIRCUIT Signals from antenna connector fed to the antenna switching circuit . In receive mode, D971 is turned off, which isolates the antenna from the transmitter circuit, so that the incoming signals are fed to the RF amplifier through L850.

* RF AMPIFIER CIRCUIT The signal, from the switching circuit, is fed to the RF amplifier Q831 through a band pass filter made up of coil, varicap diode and capacitor.

* FIRST MIXER CIRCUIT The amplified signals are fed to Gate 2 of the first mixer Q801 through C821. First local oscillator signal is supplied to Gate 1 of Q801 from the VCO circuit through C813 to convert the RF signal into the 46.35MHz first IF signal.

* IF CIRCUIT The first IF signal from Q801 is fed to the matched pair crystal filter, MCF801, then the signal is amplified in Q646. This signal is fed to IC641, which is composed of the second mixer, limiter amplifier, quadrature detector and active filter circuit. The second local oscillator at 45.9 MHz is produced at the PLL circuit by tripling its reference frequency 15.3 MHz.and is fed to the second mixer with the first IF signals to convert into 450kHz second IF signals. The second IF signals leave through pin 3,and are fed to external ceramic filters FL641,FL642 then back to IC641 (pin 5) to be amplified and detected. The detected AF signals are output from pin 9.

* Squelch (mute) CIRCUIT The squelch circuit switches off the power amplifier when no audio signal is present. The squelch circuit consists of a 16 kHz band pass filter and a noise detector circuit.

* Speaker Audio Amplifier CIRCUIT After signal detection and audio filtering, the low level audio is returned to the RF circuit via SWR101. This is then routed to Pin 1 of IC1, (TDA1517), to provide speaker audio. IC1 is enabled by a logic high applied to Q301 which in turn enables Q300, applying power to Pin 5 of IC1.The audio signal from IC641, pin 9 is applied to AF amplifier IC305-B and then fed to pin 1 of AF switching circuit IC304-A . The switched output signal on IC304-A, pin 2 is then applied to high-pass filter IC306-D, IC306-C. The cut-off frequency of this filter is controlled by the RX AUDIO FILTER line. The filtered output signal on IC306-C, pin 8 is applied to limiter IC306-B and buffer IC306-A. De-emphasis is 11 PM180V / SM-2102E SERIES MOBILE rovided by R414 and C369. The audio signal is then applied to pin 16 of level controller IC307. This device allows the CPU to control the speaker volume level(ATE mode).The level controlled signal is fed out of IC307 on pin 15 and applied to low-pass filter IC303-A. It is then applied to AF switching circuit IC304-D on pin 11, and the switched output is on pin 10. This signal is buffered by IC303-B and then amplified by AF amplifier IC1 to provide driveto the speaker. 12 PM180V / SM-2102E SERIES MOBILE 4.
